An inhibitory postsynaptic potential is produced through the hyperpolarization of the postsynaptic membrane.

Question

Quizplus · Accepted Answer

An inhibitory postsynaptic potential (IPSP) is a type of postsynaptic potential that makes the postsynaptic neuron less likely to generate an action potential. IPSPs are produced through the opening of ligand-gated ion channels that allow negatively charged ions (such as Cl-) to enter the postsynaptic neuron, causing the membrane potential to become more negative or hyperpolarized. This increase in negativity makes it more difficult for the neuron to fire an action potential, hence the inhibitory effect.
